What an engine- I looked it up and came across this info:
"The Cleveland Diesel Model 278A was extensively applied in U. S. Navy vessels, including late wartime production of fleet submarines, destroyer escorts, fleet tugs, auxiliary tugs, harbor tugs, and amphibious warfare vessels including some LSTs. It was also a popular engine in the early postwar years for use in commercial tugboats and railroad tugs."
